Quantum Simulation and Sensing with Photon Mediated Interactions

Photons bouncing back and forth many times between 
highly reflecting mirrors provide a novel way to mediate 
interactions between laser-cooled atoms held between the mirrors. Such cavity-mediated interactions provide a 
unique set of tools for both quantum sensing and 
simulation. In this talk, I will discuss our efforts to sculpt 
these interactions in order to expand the palette of cavity mediated interactions that can be realized. We have now harnessed these interactions to realize entanglement enhanced sensitivity in two leading quantum sensing platforms, matterwave interferometers and optical clocks, with future applications to new-physics searches as well as for practical timing and navigation technologies. As time permits, I will also discuss quantum simulations of dynamical phases of BCS superconductors resulting from competition of disorder and interactions following a quench.
